Earlier this template had C, P, T, and L symmetries. Nice to see someone has removed the L symmetry now. B-L Symmetry deal with baryogenesis and leptogenesis. Perhaps I am not very qualified to make this statement, but in my earnest opinion they are symmetries of a different nature and should not be considered as a part of the CPT symmetries. --Hirak 99 14:20, 7 February 2007 (UTC)
